Les batteries lithium fer phosphate (LiFePO4 ou LFP) sont les plus s\u00fbres parmi les batteries au lithium-ion traditionnelles. La tension nominale d\u2019une cellule LFP est de 3,2 V (au plomb : 2 V\/cellule). Une batterie LFP de 12,8 V est compos\u00e9e de 4 cellules connect\u00e9es en s\u00e9rie, et une batterie de 25,6 V est compos\u00e9e de 8 cellules connect\u00e9es en s\u00e9rie.<\/p>\n
Il n\u2019est pas n\u00e9cessaire de charger compl\u00e8tement une batterie LFP. La dur\u00e9e de vie s\u2019am\u00e9liore m\u00eame l\u00e9g\u00e8rement en cas de charge partielle au lieu d\u2019une charge compl\u00e8te. Cela repr\u00e9sente un avantage majeur de la batterie LFP par rapport \u00e0 la batterie au plomb.<\/p>\n
Ces batteries pr\u00e9sentent d\u2019autres avantages tels qu\u2019une large plage de temp\u00e9rature d\u2019exploitation, une performance
\nexcellente d\u2019accomplissement de cycle, une r\u00e9sistance interne faible et une efficacit\u00e9 \u00e9lev\u00e9e (voir ci-dessous).<\/p>\n
Une batterie LFP est donc la chimie de premier choix pour des applications exigeantes<\/p>\n
Pour plusieurs applications (en particulier les applications autonomes solaires et\/ou \u00e9oliennes), l\u2019efficience \u00e9nerg\u00e9tique peut \u00eatre d\u2019une importance cruciale.<\/p>\n
L\u2019efficacit\u00e9 \u00e9nerg\u00e9tique aller-retour \u2013 d\u00e9charge de 100 % \u00e0 0 % et retour \u00e0 100 % charg\u00e9e \u2013 d\u2019une batterie au plomb moyenne est de 80 %.<\/p>\n
L\u2019efficacit\u00e9 \u00e9nerg\u00e9tique aller-retour d\u2019une batterie au lithium-ion est de 92 %.<\/p>\n
Le processus de charge des batteries au plomb devient particuli\u00e8rement inefficace quand l\u2019\u00e9tat de charge a atteint 80 %, donnant des efficacit\u00e9s de 50 % ou m\u00eame moins dans le cas des syst\u00e8mes solaires quand plusieurs jours d\u2019\u00e9nergie de r\u00e9serve est n\u00e9cessaire (batterie fonctionnant avec un \u00e9tat de charge de 70 % \u00e0 100 %).<\/p>\n
En revanche, une batterie LFP atteindra 90 % d\u2019efficacit\u00e9 dans des conditions de d\u00e9charge l\u00e9g\u00e8re.<\/p>\n
70 % de gain de place.
\n70 % de gain de poids.<\/p>\n
Les batteries LFP sont tr\u00e8s ch\u00e8res par rapport aux batteries au plomb. Mais pour les applications exigeantes, le co\u00fbt \u00e9lev\u00e9 initial sera plus que compens\u00e9 par une dur\u00e9e de vie prolong\u00e9e, une fiabilit\u00e9 sup\u00e9rieure et une efficacit\u00e9 excellente.<\/p>\n
L\u2019\u00e9tat des alarmes de la temp\u00e9rature et des tensions des cellules peut \u00eatre supervis\u00e9 par Bluetooth.<\/p>\n
Fonction tr\u00e8s utile pour localiser un (\u00e9ventuel) probl\u00e8me, comme un d\u00e9s\u00e9quilibre sur les cellules par exemple.<\/p>\n
Nos batteries LFP sont \u00e9quip\u00e9es de fonctions d\u2019\u00e9quilibrage et de surveillance de cellules. Jusqu\u2019\u00e0 5 batteries peuvent \u00eatre install\u00e9es en parall\u00e8le et jusqu\u2019\u00e0 4 batteries de 12 V ou 2 batteries de 24 V peuvent \u00eatre connect\u00e9es en s\u00e9rie : ainsi un banc de batterie de 48 V jusqu\u2019\u00e0 1500 Ah peut \u00eatre assembl\u00e9. Les c\u00e2bles d\u2019\u00e9quilibrage\/surveillance de cellules peuvent \u00eatre raccord\u00e9s en s\u00e9rie, et ils doivent \u00eatre connect\u00e9s \u00e0 un Syst\u00e8me de gestion de batterie (BMS)<\/p>\n
